Description
本发明涉及空调技术领域，具体涉及一种加湿系统、空调器及其加湿控制方法。The invention relates to the technical field of air conditioners, and in particular to a humidification system, an air conditioner and a humidification control method thereof.
随着社会的发展和生活水平的提高，人们对选购家用电器的要求也越来越高。以空调为例，在冬季使用空调时，人们对空调的要求不仅仅体现在空调能调节房间的温度，而且还体现在空调能调节房间的湿度上，只有温度和湿度均处于合理的区间，这样的房间才会更加舒适，所以对于空调来说，在温度调节的基础上，研究可以加湿的空调系统具有非常重要的意义。With the development of society and the improvement of living standards, people are increasingly demanding the purchase of household appliances. Taking air conditioners as an example, when using air conditioners in winter, people's requirements for air conditioners are not only reflected in the air conditioner's ability to adjust the temperature of the room, but also in the air conditioner to adjust the humidity of the room, only the temperature and humidity are in a reasonable range, so The room will be more comfortable, so for air conditioning, on the basis of temperature regulation, it is very important to study the air conditioning system that can be humidified.
传统的空调设计一般都不具备加湿功能，为解决此问题，一部分空调厂商采用在空调中设置膜处理装置来实现空调的加湿功能。具体而言，该解决方案是在传统空调中设置带有湿膜的加湿装置实现室内的加湿。其主要原理为：利用湿膜只允许水分子通过的特性，在膜两侧驱动力(如压差、浓度差、温度差)的作用下，经过湿膜的潮湿空气中的水分子透过湿膜被送入室内，进而实现加湿效果。这种方案具有操作方便、分离效率高、能耗低等优点。但是在实际应用中，由于膜材料的亲水性，水分子很容易在渗透侧聚积，使后续透过速率降低，导致加湿性能急剧下降、加湿不均匀等现象出现，影响用户的使用体验。也就是说，现有空调的加湿系统存在加湿效果差的问题。Traditional air conditioning designs generally do not have a humidifying function. To solve this problem, some air conditioner manufacturers use a membrane processing device in the air conditioner to realize the humidifying function of the air conditioner. Specifically, the solution is to provide a humidification device with a wet film in a conventional air conditioner to achieve humidification in the room. The main principle is: the use of wet film allows only the passage of water molecules, under the action of driving forces on both sides of the membrane (such as pressure difference, concentration difference, temperature difference), the water molecules in the humid air passing through the wet membrane pass through the wet The film is sent into the room to achieve a humidifying effect. This solution has the advantages of convenient operation, high separation efficiency and low energy consumption. However, in practical applications, due to the hydrophilicity of the membrane material, water molecules are easily accumulated on the permeate side, which reduces the subsequent transmission rate, resulting in a sharp decrease in humidification performance and uneven humidification, which affects the user experience. That is to say, the humidification system of the existing air conditioner has a problem that the humidification effect is poor.

As shown in FIG. 1, in order to solve the problem of poor humidification effect existing in the humidification system of the prior air conditioner, the humidification system of the present invention mainly includes a dehumidification membrane group 11, which is usually disposed outdoors, an isolation valve 12, a vacuum pump 13, and a part disposed indoors. Humidifying unit. The vacuum pump 13 is connected to the dehumidifying membrane group 11 through the isolation valve 12 for evacuating the dehumidifying membrane group 11 to form a negative pressure in the dehumidifying membrane group 11, thereby causing a pressure difference between the dehumidifying membrane group 11 and the outside air to cause water molecules. Enter the dehumidifying membrane group 11. The humidifying unit further includes a first compressor 14 that is normally disposed outdoors and a humidifying membrane group 15 that is generally disposed indoors, and the first compressor 14 is connected to the dehumidifying membrane group 11 and the humidifying membrane group 15, respectively, for the dehumidifying membrane group 11 The accumulated moisture is pressurized and sent to the humidifying membrane group 15 and thus sent into the room to humidify the indoor air.

当需要进行加湿操作时，首先打开隔离阀12，利用真空泵13对除湿膜组11进行抽真空，从而在除湿膜组11内形成负压，此时室外除湿膜组11附近空气中的水蒸气会进入除湿膜组11。当除湿膜组11内的水蒸气含量达到一定程度时，打开第一压缩机14，对除湿膜组11内的水分进行加压并输送到加湿膜组15，此时由于加湿膜组15内的水蒸气分压高于室内干燥空气中的水蒸气分压，加湿膜组15内的水蒸气会自然地排放到室内环境中。When the humidification operation is required, the isolation valve 12 is first opened, and the dehumidification membrane group 11 is evacuated by the vacuum pump 13, thereby forming a negative pressure in the dehumidification membrane group 11, and at this time, the water vapor in the air near the outdoor dehumidification membrane group 11 will Enter the dehumidifying membrane group 11. When the water vapor content in the dehumidifying membrane group 11 reaches a certain level, the first compressor 14 is opened, and the moisture in the dehumidifying membrane group 11 is pressurized and sent to the humidifying membrane group 15, at this time due to the inside of the humidifying membrane group 15. The partial pressure of water vapor is higher than the partial pressure of water vapor in the indoor dry air, and the water vapor in the humidifying membrane group 15 is naturally discharged into the indoor environment.
从上述描述可以看出，通过加湿单元的设置，本发明的加湿系统能够快速有效地将除湿膜组11内产生的水分通过第一压缩机14加压后透过加湿膜组15送入室内，保证了除湿膜组11内水分的平衡，使加湿系统的运行更加稳定，解决了现有技术中加湿系统加湿效果不稳定的问题，改善了用户体验。此外，从上述描述还可以看出，本发明的加湿系统可以实现无水加湿的功能，即无需人为定期加水，直接从室外空气中进行取水，再转化到室内进行加湿，从而避免了人为加水等问题，提高了用户体验。As can be seen from the above description, the humidification system of the present invention can rapidly and efficiently pressurize the moisture generated in the dehumidification membrane group 11 through the first compressor 14 and then into the room through the humidification membrane group 15 by the arrangement of the humidification unit. The balance of moisture in the dehumidifying membrane group 11 is ensured, the operation of the humidifying system is more stable, and the problem of unstable humidification of the humidifying system in the prior art is solved, and the user experience is improved. In addition, as can be seen from the above description, the humidification system of the present invention can realize the function of no water humidification, that is, no need to artificially add water, directly take water from the outdoor air, and then convert it into indoors for humidification, thereby avoiding artificial water addition, etc. The problem is to improve the user experience.
需要说明的是，本实施方式中，除湿膜组11和加湿膜组15可以采用相同结构，并采用正反接的方式以实现除湿膜组11和加湿膜组15的功能。此外，针对不同地区和不同环境，除湿膜组11和加湿膜组15内的有机膜或无机膜的层数不同，配置的第一压缩机14的型号也不尽相同，因此本领域技术人员可以针对不同的应用场景对除湿膜组11、加湿膜组15的层数以及第一压缩机14的型号作出具体调整，本实施例中不对其作具体限制。In the present embodiment, the dehumidifying membrane group 11 and the humidifying membrane group 15 may have the same structure and adopt a positive and negative connection to realize the functions of the dehumidifying membrane group 11 and the humidifying membrane group 15. In addition, for different regions and different environments, the number of layers of the organic film or the inorganic film in the dehumidifying film group 11 and the humidifying film group 15 is different, and the type of the first compressor 14 disposed is also different, so that those skilled in the art can The specific adjustment of the number of layers of the dehumidifying film group 11, the humidifying film group 15, and the model of the first compressor 14 for different application scenarios is not specifically limited in this embodiment.

作为一种优选的技术方案，除湿膜组11、隔离阀12、真空泵13、第一压缩机14、第二压缩机21、四通阀22、第一换热器231、第一风机281、节流元件24、单向阀25、高压截止阀261以及低压截止阀262设置于空调器的室外机，加湿膜组15、第二换热器232、第二风机282以及气液分离器27设置于空调器的室内机。As a preferred technical solution, the dehumidification membrane group 11, the isolation valve 12, the vacuum pump 13, the first compressor 14, the second compressor 21, the four-way valve 22, the first heat exchanger 231, the first fan 281, and the section The flow element 24, the check valve 25, the high pressure shutoff valve 261, and the low pressure cutoff valve 262 are disposed in the outdoor unit of the air conditioner, and the humidifying membrane group 15, the second heat exchanger 232, the second fan 282, and the gas-liquid separator 27 are disposed at The indoor unit of the air conditioner.
上述设置方式的优点在于：通过在传统空调中设置一套独立的加湿系统，使得温度调节系统与加湿系统能够彼此独立运行，进而实现温湿度独立控制。进一步地，当温度调节系统与加湿系统同时运行时，由于室内潮湿空气被加湿系统加湿，即空气的潜热部分增加，因此温度调节系统只需处理进入系统的湿润燥空气的显热部分即可。也就是说，较传统空调器而言，本发明的带有加湿系统的空调器还具有提高能效的效果。The advantage of the above arrangement is that by providing a separate humidification system in the conventional air conditioner, the temperature adjustment system and the humidification system can operate independently of each other, thereby achieving independent control of temperature and humidity. Further, when the temperature adjustment system is operated simultaneously with the humidification system, since the indoor humid air is humidified by the humidification system, that is, the latent heat portion of the air is increased, the temperature adjustment system only needs to process the sensible portion of the humid dry air entering the system. That is to say, the air conditioner with a humidifying system of the present invention has an effect of improving energy efficiency as compared with a conventional air conditioner.
当然，上述优选的布置方式仅仅用来阐述本发明的技术原理，并非用于限制本发明的保护范围，在不偏离本发明原理的前提下，任何设置形式的改变都落入本发明的保护范围之中。例如，气液分离器27还可以设置于室外机中，第一压缩机14和/或第二压缩机21设置于室内机中等。The above-described preferred arrangements are merely used to illustrate the technical principles of the present invention, and are not intended to limit the scope of the present invention.
